Styrofoam and Gasoline as Alternative Sealant

Review of Related Literature

Scope and Limitations

  • Only limited for Styrofoam since it can be melted by gasoline; not all plastic materials can melt in gasoline
  • Special XCS was the gasoline that was used
  • No materials were bought in the market since this study aims to use recyclable materials
  • An amount of P50.00 was used for gasoline

Styrofoam

Gasoline

  • Gasoline is a fuel derived from petroleum crude oil used for engines
  • An organic substance
  • A volatile substance and is stable if stored properly
  • Flow rate and viscosity

  • Styrofoam is the brand name for a type of polystyrene invented by Dow Building Solutions in the mid-20th century.
  • Generic term for expanded polystyrene foam (disposable coffee cups)
  • It is not a biodegradable material.
  • When heated above its glass transition temperature, it turns to liquid form and becomes solid again when it cools off
  • It dissolves in some organic solvents

Sealant

  • Sealant is a viscous material that changes state to become solid, once applied
  • Used to prevent the penetration of air, gas, dust, fire, smoke or liquid from one location through a barrier into another
  • Known to be a viscous material which turns to solid after application

Objectives

Results and Discussion

This study aims to produce an alternative sealant made out of Styrofoam and gasoline, and to compare its effectivity to the commercial one in terms of,

1.) duration of dryness (the time for sealant to dry)

2.) its adhesiveness and

3.) its water resistance

Set-up 1

(Commercial

Significance of the Study

Water

Resistance

5 – 10

minutes

MATERIALS

500 ml of gasoline

Styrofoam

Commercial Sealant

two 4x4 galvanized iron

APPARATUS

2 clean container

Procedure

Product cannot be removed easily from the galvanized iron.

Water cannot pass through the holes.

Rationale

If this study will be successful, then it would be of great help and contribution to the school and to the environment. People who are experiencing financial problems can benefit from this study because it is much cheaper and less expensive than the commercial sealant since the materials used in this alternative sealant are only recycled.

Set-up 2

(Alternative

Sealant)

Prepare and gather the materials needed. Place the Styrofoam on a clean container. Cut it into smaller pieces. Next, pour the 500 ml gasoline, which is placed on the second container, into the first container with the Styrofoam on it. Mix the mixture and wait until it turns viscous.

15 – 20

minutes

Product sticks to the roof but may lose its effectiveness if removed for a number of times.

Water cannot pass through the holes.

Problem

Can Styrofoam and gasoline combined become a sealant? If so, does it have the same effects with the commercial sealant? These are the problems that the researchers would like to find out.

Conclusions

Styrofoam dissolves in organic solvents and gasoline is an example of such. Since gasoline is flammable, this causes the Styrofoam to melt, gradually turning it into a sealant after mixing. After thorough experimentation on this investigatory project, one can conclude that Styrofoam and gasoline combined will create an alternative sealant.

  • Philippines as a tropical country.
  • Rusting on roofs causing easy breakage
  • A more economical way of making a roof sealant by recycling used Styrofoam
  • An urge to know if this alternative sealant can be effective on roofs

Recommendations

When polystyrene is heated above its glass transition temperature, it turns into liquid form. It becomes solid again when it cools off. Since gasoline is flammable, this causes the Styrofoam to melt, turning it into a sealant. After thorough experimentation on this investigatory project, one can conclude that Styrofoam and gasoline combined will become a sealant.

The next researchers can test whether the product is flame resistant and to also use other types of gasoline aside from the Special XCS.
